To all whom it may concern:

Be it known that I, HARRY CRAIGHITJ. BADDER, a subject of the King of Great Britain, and resident of Liverpool, England, have invented certain new and useful Improvements inl Doors, of which the followin is a specification. v

his invention relates to improvements in the construction of doors, lpanelings, or the like, of that type in whic the framework or structure is built up of metal whether of assembled channel sections, or corrugated sheet metal, the intersticesin the structure being lfilled in with refractory material or cement. The particular features of the. resent 1nvention consist in constructing t e framework of the door, paneling or the like, of a light multi-cellular character formed vby a series of metal bands or strips separated by distance pieces and secured' together by bolts, screws, or rods passing vthrough the strips. Or the cellular character of the framework may be obtained by the use of corrugated sheet metal. The interstices 1n the framework may beafterward filled in with asbestic cement, the framework being finally inclosed with sheet metal orasbestic boards. v

-y The invention is illustrated in the accompanying drawings which show the appllca- Y tion of the invention to the construction of doors, or other fittings. y

Figure l. is an elevation partly broken away to show the interior cellular construction of'a door made up of metal strips in accordance with this invention. Fig. .2. 1s a fragmentary vertical section on the line A--A of Fig. 1., and'Fig. 3. is a plan 1n section on the line B--Bof Fig. 1. Fig. 4.

is an enlarged detail of a portion of Fig. 2.l

showin a section through the top horizontal rail an a method of attaching the panel. Fig. 5. being an analogous detail of a part of` Fig. 3. Figs. 6. and 7. are respectively a front elevation and sectional plan on the line C-C of Fig. 6. showing a modified form of the invention, the cellular construction of the door bein attained by the use of curved-corrugated eet metal. Fig. 8. is an analogous View to Fig. 7, but with angular corruoated metal. Figs. 9. and 10: show further forms of corrugated metal construction, Fig. 10. being a sectional plan on the line D-D of Fig. 9.

In theforln illustratedinFigs. 1. to 5.

inclusive, the horizontal rails and vertical door frame Stiles 1. and 2. are built up of a series of thin metal vbands or strips 3, preferably arranged vertically as shown, the inner and outer strips 4 of the vertical stiles being of heavier gage metal than the remaining strips. The strips are placed edgewise with reference to the thickness of the doorand'* are held or spaced apart by distance pieces 5 fitted between the strips, these distance pieces being of Vany suitable section but preferably of tubular or hollow rectangular' section as indicated in Fig. 4. The strips and distance pieces are then secured together by bolts or screws 6 or the may,

be riveted. If screwed, an additiona strip 7 may be brazed or otherwise attached along the interior of the outer strip 4 to provide more metal for the threaded end 6a of the securing bolt whichl is screwed therein. A

recess 8 is left in the stile to receive the lock.

The stiles and rails after being made in the way described so as to form a cellular structure are filled in if desired with asbestic cement, mineral wool, or other filling, V and then inc losed by a sheet metal outer casing 9, the inner ends or flanges 9a of the casing being brought together centrally, as indicate more clearly in Fig. 4.,-so that they lmay be caused to 'envelop the edges ofy the metal panel l0 to which they are riveted at 11. The fastening of `the fianges 9a to the panels 10 is hidden by the sheet metal moldings 12 which are brazed or otherwise joinedat 12a to the panels and Stiles. Fancy embossed sheet metal fittings may be placed over the miter junctionsl of the moldings, and in lieu of covering the stiles and rails ly and 2 with a sheet metal casing as described they may be covered with asbesticiboards fitted in the same way as the sheet metal.

In the modifications shown in Figs. 6 to 10 inclusive, the cellular framework of the vertical Stiles 1 is obtained by constructing them from lengths of corrugated metal 14 the corrugations running lengthwise, the

horizontal rails being similarly constructed ofcorrugated metal 15 but with the corrugations running transversely to the length of the rail. The corrugations of the vertical and horizontal lengths ofmetal fit in together at the corners of the frame and the metal at these points may be permanently fastenedtogether and the corrugated lengths if desired be reinforced by screws or bolts l passing through the corrugations in a similar fashion to the bolts 6 of the revious modification. A sheet metal cellu ar structure is thus obtained and may be filled in With asbestic cement mineral wool or other filling and is then inclosed by a casing of sheet metal 9 as before described and connected to the paneling;

Doors, partitions, or the like, constructed in the Way described if left plain may be afterward painted to imitate Wood, or they may be rendered very ornate in appearance by forming the outer casing of embossed sheet metal. lIl hey also oer many practical advantages as they are' very light, cannot shrink or split, and are not liable to Warp, and being constructed entirely ot metal and asbestic cement or boards they are extremely fire-resisting, the lling of asbestic cement, mineral Wool, or the like, tending further to give the door great sound deadening qualities.

l claim:

l. A framed metallic door or paneled structure comprising a rail and stile frame work of sheet metal construction inclosing tubular distance pieces, a sheet metal casing inclosing the framework, and metal panels secured to said casing. l

2. A framed metallic door or paneled structure the rail and stile framework of which is built up of metal bands or strips assembled edgewise relatively to the thickeeeioe ness of the frame, tubular distance pieces separating said strips and securing bolts passing through the distance pieces and strips.

3. A framed metallic door or paneled structure the rail and stile framework of which is built u of metal bands or strips assembled edgewlse relatively to the thickness of the frame, tubular distance pieces separating said strips, the multi-cellular structure thus obtained being lled in With refractory cement and inclosed in a sheetmetal outer casing.

4. A framed metallic door or paneled structure comprising: a rail and stile framework built up of metal bands or stripsassembled edgewise relatively to the thickness of the frame, tubular distance pieces separating said strips, securing bolts passing through the distance pieces and strips, a filling of refractory cement in the interstices of the rails and Stiles, a sheet metal outer casing inclosing said rail and stile framework, panels secured to said outer casing, and sheet metal moldings covering the une tion of the panels and the outer casing.

in Witness whereof i have hereunto set my hand in presence of two Witnesses.
